Application filed April 12, 1924. Serial No. 706,158.

To all whomz't may concern Be it known that I, LOVIAS FAIRY FRASER, acitizen of the United States, residing at Drumright, in the county ofGreek and State of Oklahoma, have invented new and useful Improvementsin Jack-Post Bearings, of which the following is a. specification.

This invention relates to jack posts, commonly used in oil fields, andcontemplates a structure which eliminates the use of many timbers whichare used as a base or foundation for the posts in present day use, andthus provide a post that is more durable, cheaper to install, and onewhich can be quickly and conveniently disassembled and used again shoulda well be abandoned.

The nature and advantages of the invention will be better understoodwhen the following detailed description is read in connection with theaccompanying drawings, the invention residing in the construction,combination and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals ofreference indicate similar parts in the several views, and wherein:

Figure 1 is a view in elevation of the invention.

Figure 2 is a top plan view.

Figure 3 is a sectional view taken on the line 38 of Figure 1.

Figure 4L is a sectional view taken on the line 4cl of Figure 1.

Figure 5 is an end elevation of one part of the bearing.

Figure 6 is a similar view of the other part of the bearing.

Referring to the drawings in detail, 10 represents an elongated basemember which is adapted to be bolted or otherwise suitably secured to aconcrete foundation 11. Rising centrally from this base is a solidtubular portion 12 which is adapted to be received by the adjacent endof a metallic casing 13 which constitutes the post. It will be notedupon inspection of Figure 1 that the tubular portion 12 is slightlyreduced to form a shoulder 14 at its point of juncture with the base,that the lower end of the post reposes on this shoulder.

Supported upon the post is a. two part bearing, the respective parts ofwhich are illustrated in Figures 5 and 6, the lower part 15- which. isformed with a centrally. de-. pressed portion 16: as shown.

of. the bearing includingan elongated-- platei Depending-1 from thisdepressed. portion is a tubulaia.

member 17"sim'ilar to the tubular portion 12} above referred to, andwhich tubular member 17 is adapted to be received by the adjacent end ofthe post or casing 13. The tubular member is formed to provide ashoulder 18 which rests upon the upper end of the post as clearly shownin Figure 4. The upper part of the bearing consists of an elongatedplate 19 which is considerably shorter than the plate 15 of the lowerpart of the bearing, and is formed with a centrally bulged portion 20 asillustrated in Figure 1. This portion of the bearing is also formed witha reinforcing rib 21 which is arranged longitudinally of the bulgedportion 20. The upper part of the bearing reposes upon the lower part,and these parts are secured together by fastening elements 22 which areadapted to pass through aligned openings. In addition to these fasteningelements 22 the respective parts of the bearings are held associated bystay rods 23 passed through aligned openings adjacent the corners of thebearing and having their lower ends embedded in the concrete foundation.Rising from the opposed ends of the plate 15 are spaced a-pertured lugs24, these lugs being obliquely disposed and closely associated toreceive therebetween stay rods 25 which extend from the ends of thelower part of the bearing in the direction of the ground where they aresecured at points remote from the bearing proper. The rods 25 are heldpositioned between the lugs 24 by means of nuts 26. It is to beunderstood that the various parts of the invention can be constructedfrom any suitable material and also vary in size without departing fromthe spirit of the invention. Furthermore, it

is manifest that the construction is a durable one requiring practicallyno upkeep as there is nothing to wear, and that the component parts ofthe invention can be quickly and conveniently assembled and disassembledas the occasion may require.

While it is believed that from the foregoing description, the nature andadvantages of the invention will be readily apparent, I desire to haveit understood that I do not limit myself to what is herein shown anddescribed, and that such changes may be resorted to when desired as fallWithin the scope of what is claimed.-

Having thus described the invention, I claim:

In a post of the character described, a base including a tubular portionrising centrally therefrom, an annular shoulder formed on the tubularportion, a casing adapted to be fitted over said tubular portion andhavingtits lower end reposing .on said shoulder, aztwo partbearingarranged upon saidlcasing, one part of the bearing being relatively longand including'a tubular portion depending therefrom and adapted to bereceived by the adjacent end of the easing, a shoulder formed on saidtubular portion, to bear against said casing, means for securing therespective parts of the bearing together, stay rods passed throughaligned openings in both parts of the bearing, spaced apertured lugsrising from the opposed ends of the first mentioned part of the bearing,stay rods having their adjacent ends adapted to be positioned betweensaid lugs, and a reinforcing rib extendedacross the second mentionedpart ofsaid bearing.

In testimony whereof I aflix my signature.

I LOVIAS FAIRY FRASER.
